SPECIFICATION forming part of "Letters Patent No. 704,747, datedJuly15,1902.

Application filed ma 20.1 02. Serial No. 94,966. (its model.) A

To all whom it may concern/.-

Be it known;that we, CHARLES Jonnson' and OREN G. RAWLEY, citizens oftheUnited States, residing at Newark Valley, in the county of Tioga andState of New York, have invented a new and'usef-ulFertilizer-Distributer, of which the following is a specification.

This invention is an improved construction of fertilizer-distributor,the object being to provide a simple and cflicient'construction wherebyfertilizing material of. any character whatever can be evenlydistributedover a field without clogging the operative parts of the machine,and=another objectis to'pro vide a fertilizer-distributor in whichthedistributing mechanismcan be quickly and easily adjusted by-theoperation of a single lever, so thatthe rate of feedor distribution canbe regulated, and this is accomplished while the machine isin operation.

With these objects insview-the invention consists in the novel featuresof construction and combination, allof whichwillcbe fully describedhereinafter and pointed out in the claims. W .m

In thedrawings forming. part ofthis specification, Figure lis aperspective view'illusn trating a fertilizer-distributor constructedinaccordance with our invention. Fig.2 is a vertical longitudinal sectionshowing the' wagon-body, endless belt or apron, and diss of thewagon-body A is cut-away at the front and rear ends to permit theoperation of an endless belt or apron B, which is composed vof a seriesof cross-slats B, connected to the links B said links traveling aroundand operated by sprockets B mounted upon the shafts, journaled in thesills of the wagon-V body. Channel-bars B are arranged upon the'bottomof the wagon-body. and serve as guides for the links or'chains-of theendless belt or apron. The sills of the wagon-body areextend'ed ashortdistance beyond the endgate, as shown at A in Figs. 1 and 4, andjournaled between the projecting. ends is a distributing-drum G, thesurface of which is provided with a series of spikes or fingers C, andit will be noted that the center of said drum or cylinder, is inalinement with the, upper flight of the feed apron or belt. Theend-gateD is curved upon the arc of a circle, as indicated, and slides inguideways D, produced in the sides of the wagon-body, and by sliding thesaid end-gate up or down the sizeof the opening at the rear end ofthewagon body can be increased or decreased, therebypermitting a larger orsmaller quantity offertilizer to be fed from the wagon-body. Brackets Dare attached to the cross-strip Diahove the sliding end 4 gate,saidbracket's having set- .screws D passing therethrough' and bindingagainst the upwardly-projecting portion of the end-gate, so'thatthe.said lend-gate can be locked in any adjusted position. By having thedistributing-drumarranged with its center on a line with the uppenflightof the feed apron or belt an even'oruniform distribution of thefertilizer is obtained and all clogging-of the parts entirelyavoided.

In order to operate the'feed belt or apron uniformly and also to providefor the regulation ofsuch movement, :We have devised an improved formofoperating mechanism in which we employ an eccentric E, which is mountedupon the rearaxle of the wagon, said eccentric being surrounded by astrap E, to which is pivotally connected a link F, said link beingpivoted at F to the sill of the wagon-body, and sliding in the said linkis the pin Gr, carried upon the forward end of.

the rod H, said rod being suspended by means of a bar I, whichis'pivotally connected at its upper end' to asdisk K, the upper edge ofwhich is provided with rack-teeth K, adapted for engagement with therack-bar L, said bar being operated by means of the hand-lever L, aguide-roller L holding the rack-bar in engagement with the rack-teethdisk K, and

it will be understood that by shifting the lever L the disk K is turned,so that the rod H is raised or lowered, and inasmuch as the link ispivotally connected to the straps surrounding the eccentric the throw ofthe said rod will be regulated. The rear end of the rod H is bifurcated,as shown at H, and works upon the projecting end of the rearsprocket-shaft H and mounted upon the end of said shaft is aratchet-wheel M, and pivotally connected to the bar H are the pawls Nand N, which engage the ratchet-wheel M and are held in such engagementby means of the spring N connecting said pawls; and it will be notedthat the pawl N engages the upper side of the ratchet-wheel and that thepawl N engages the lower side thereof and is hooked at its end, so thatupon the rear stroke of the rod H the pawl N will operate and upon theforward stroke the pawl N will operate, so that a continuous rotarymotion is imparted to the rear sprocket-shaft, and in this manner theendless feeding belt or apron is moved continuously in a rearwarddirection, thereby feeding the fertilizer out through the opening to thedistributing drum or cylinder, and by operating the hand-lever theoperating mechanism can be regulated so that the amount of fertilizer tobe distributed can be regulated with accuracy. One end of thedistributing-drum shaft projects beyond the sill and is provided with asprocket-wheel 0, around which travels a drive-chain P, said chainpassing around a sprocket Q, which is mounted upon a shaft Q, carrying agear Q which meshes with another gear Q mounted upon the rear axle ofthe wagon, so that as the wagon is being driven forward and the feedingmechanism operated the drum will be rotated to distribute the fertilizerfed thereto by the apron or belt. A suitable clutch or pawl-and-ratchetmechanism (not shown) is arranged in the hub of the rear axle, so thatthe operating mechanisms will only be operated during the forwardmovement of the wagon.

It will thus be'seen that we provide a simple, efficient, and durableconstruction of fertilizer-distributer and one in which an even anduniform feed and distribution can be had and also one in which theamount of fertilizer to be distributed can be quickly and easilyregulated while the machine is in operation.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a fertilizer-distributor, the combination with a wagon-body, of anendless feedbelt, an adjustable tail-gate, a distributingdrum inproximity to said tail-gate, means for rotating said drum, an eccentricmounted on the axle-shaft, a pivoted lever connected with saideccentric, and means connected with said lever for imparting rotation tosaid endless belt, substantially as described.
